Question

Which equation defines a function with a zero at 7?

A. y = x2 + 7x + 10
B. y = x2 + 9x + 14
C. y = x2 – 9x + 14
D. y = x2 – 7x + 10

Answer 1

option C

Explanation:

the solutions to function x^2 -9x +14 are (x-7) and (x-2)

through the zero product property

(x-7)=0

x=7

and

(x-2)=0

x=2

this is what I looked up and got..hope it helps
